Stale Tag Management

Stale tags are tags that have no new data samples within a specified period of time. These tags add to system overhead and slow down user queries. The Data Store Configuration option allows system administrators to configure the time period after which tags are considered stale and how often the system should check for stale tags.

Under the default configuration, tags are never considered stale. This effectively disables stale tag management.

To see the names and descriptions of all currently stale tags, use the IsStale criteria in a tag search.

To improve performance, permanently delete unused tags. Perform a tag search using the IsStale criteria and select Permanently Delete Tag.
